Abstract
A plate heat exchanger includes a plurality of heat transfer plates stacked together and each having openings at four corners thereof. The heat transfer plates are partially brazed together such that a first flow passage through which first fluid flows and a second flow passage through which second fluid flows are alternately arranged with one of the heat transfer plates disposed therebetween, openings at the four corners being connected forming first headers through which the first fluid enters and is discharged and second headers through which the second fluid enters and is discharged. At least one of two heat transfer plates between which the first flow passage or the second flow passage is disposed is formed by a pair of metal plates stacked together. The metal plate adjacent to the second flow passage is thinner than the metal plate adjacent to the first flow passage.
